Optical Amplifier
Optical Amplifier uses proven Erbium-Doped Fiber (EDF)
technology to allow amplification of an optical signal without the use
of costly regenerative repeater stations. Hence, it's distinct advantage
is that it increases the allowable distance between each site before
signal begins to degrade. The transmission distance is more than 100km
before the signals need to be regenerated.
Diagram below show different type of amplifier and it's position along the transmission distance.
Typically, eWAVE provides 3 different type of Optical amplifier for long distance transmission.
Dispersion Compensation Module
Amplified DWDM systems experience accumulated delay induced by
chromatic dispersion on long fiber spans. Dispersion Compensation
Modules (DCMs) are used to control this delay. Chromatic dispersion is
predictable and stable and can be compensated for using dispersion
compensation modules. A single-slot DCM module is simply added to the
system as needed.
eWAVE DCM's have low insertion loss, exceptional linearity and low
latency. They can be placed anywhere including pre, post or mid stage
applications.
